* ipmi: Add shutdown functions for users and interfacesCorey Minyard2018-04-181-0/+6
| | | | | | | | | | | Since things that IPMI uses can be hot-swapped, the users and interfaces really need to be able to handle this.

* ipmi: Make ipmi_demangle_device_id more genericJeremy Kerr2017-09-271-12/+12
| | | | | | | | | | | | | | | | | | Currently, ipmi_demagle_device_id requires a full response buffer in its data argument. This means we can't use it to parse a response in a struct ipmi_recv_msg, which has the netfn and cmd as separate bytes. This change alters the definition and users of ipmi_demangle_device_id to use a split netfn, cmd and data buffer, so it can be used with non-sequential responses. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Fixed the ipmi_ssif.c and ipmi_si_intf.c changes to use data from the response, not the data from the message, when passing info to the ipmi_demangle_device_id() function.

* ipmi: Don't flush messages in sender() in run-to-completion modeHidehiro Kawai2015-09-031-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When flushing queued messages in run-to-completion mode, smi_event_handler() is recursively called. flush_messages() smi_event_handler() handle_transaction_done() deliver_recv_msg() ipmi_smi_msg_received() smi_recv_tasklet() sender() flush_messages() smi_event_handler() ... The depth of the recursive call depends on the number of queued messages, so it can cause a stack overflow if many messages have been queued. To solve this problem, this patch removes flush_messages() from sender()@ipmi_si_intf.c. Instead, add flush_messages() to caller side of sender() if needed. Additionally, to implement this, add new handler flush_messages to struct ipmi_smi_handlers. Signed-off-by: Hidehiro Kawai <hidehiro.kawai.ez@hitachi.com> Fixed up a comment and some spacing issues.

* ipmi: Turn off all activity on an idle ipmi interfaceCorey Minyard2014-04-171-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | The IPMI driver would wake up periodically looking for events and watchdog pretimeouts. If there is nothing waiting for these events, it's really kind of pointless to be checking for them. So modify the driver so the message handler can pass down if it needs the lower layer to be waiting for these. Modify the system interface lower layer to turn off all timer and thread activity if the upper layer doesn't need anything and it is not currently handling messages. And modify the message handler to not restart the timer if its timer is not needed. The timers and kthread will still be enabled if: - the SI interface is handling a message. - a user has enabled watching for events. - the IPMI watchdog timer is in use (since it uses pretimeouts). - the message handler is waiting on a remote response. - a user has registered to receive commands. This mostly affects interfaces without interrupts. Interfaces with interrupts already don't use CPU in the system interface when the interface is idle.

* device.h: audit and cleanup users in main include dirPaul Gortmaker2012-03-161-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The <linux/device.h> header includes a lot of stuff, and it in turn gets a lot of use just for the basic "struct device" which appears so often. Clean up the users as follows: 1) For those headers only needing "struct device" as a pointer in fcn args, replace the include with exactly that. 2) For headers not really using anything from device.h, simply delete the include altogether. 3) For headers relying on getting device.h implicitly before being included themselves, now explicitly include device.h 4) For files in which doing #1 or #2 uncovers an implicit dependency on some other header, fix by explicitly adding the required header(s). Any C files that were implicitly relying on device.h to be present have already been dealt with in advance. Total removals from #1 and #2: 51. Total additions coming from #3: 9. Total other implicit dependencies from #4: 7. As of 3.3-rc1, there were 110, so a net removal of 42 gives about a 38% reduction in device.h presence in include/* Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
* include: replace linux/module.h with "struct module" wherever possiblePaul Gortmaker2011-10-311-1/+0
| | | | | | | | | | | | | | | | | | | | | The <linux/module.h> pretty much brings in the kitchen sink along with it, so it should be avoided wherever reasonably possible in terms of being included from other commonly used <linux/something.h> files, as it results in a measureable increase on compile times. The worst culprit was probably device.h since it is used everywhere. This file also had an implicit dependency/usage of mutex.h which was masked by module.h, and is also fixed here at the same time. There are over a dozen other headers that simply declare the struct instead of pulling in the whole file, so follow their lead and simply make it a few more. Most of the implicit dependencies on module.h being present by these headers pulling it in have been now weeded out, so we can finally make this change with hopefully minimal breakage.

* IPMI: Add one interface to get more info of low-level IPMI deviceZhao Yakui2010-12-141-0/+8
| | | | | | | | | | | | | | | | | | | The IPMI smi_watcher will be used to catch the IPMI interface as they come or go. In order to communicate with the correct IPMI device, it should be confirmed whether it is what we wanted especially on the system with multiple IPMI devices. But the new_smi callback function of smi_watcher provides very limited info(only the interface number and dev pointer) and there is no detailed info about the low level interface. For example: which mechansim registers the IPMI interface(ACPI, PCI, DMI and so on). This is to add one interface that can get more info of low-level IPMI device. For example: the ACPI device handle will be returned for the pnp_acpi IPMI device.

* proc 2/2: remove struct proc_dir_entry::ownerAlexey Dobriyan2009-03-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy as correctly noted at bug #12454. Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it. Kudos to Jeff Layton for reminding about this, let's say, oversight. http://bugzilla.kernel.org/show_bug.cgi?id=12454 Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>

* [PATCH] IPMI: Add maintenance modeCorey Minyard2006-12-071-0/+7
| | | | | | | | | | | | | | | Some commands and operations on a BMC can cause the BMC to "go away" for a while. This can cause the automatic flag processing and other things of that nature to timeout and generate annoying logs, or possibly cause other bad things to happen when in firmware update mode. Add detection of those commands (cold reset, warm reset, and any firmware command) and turns off automatic processing for 30 seconds. It also add a manual override either way.

* [PATCH] ipmi: add full sysfs supportCorey Minyard2006-03-261-2/+45
| | | | | | | | | | | | | | | | | | | | | | | | Add full driver model support for the IPMI driver. It links in the proper bus and device support. It adds an "ipmi" driver interface that has each BMC discovered by the driver (as a device). These BMCs appear in the devices/platform directory. If there are multiple interfaces to the same BMC, the driver should discover this and will only have one BMC entry. The BMC entry will have pointers to each interface device that connects to it. The device information (statistics and config information) has not yet been ported over to the driver model from proc, that will come later. This work was based on work by Yani Ioannou. I basically rewrote it using that code as a guide, but he still deserves credit :).

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+156
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
